Power Sony's A7S from an external power source for extended run-times with theLR-16 dummy cable. This allows the use of more powerful V-Lok batteries 
VL-70 or if you wish to keep weight to a minimum our BPU range of batteries 
BP-60U can also be used. 
No further regulation is required as the LR-16 is regulated to the correct voltage the A7S requires.
